PRIMING-CUP.

Application filed May 19,

T 0 aZZ whom it may concern:

Be it known that I, CHAnLns Gr. ANDER son, Jr., a citizen of the UnitedStates, residin at Buffalo, in the county of Erie and btate of New York,have invented certain new and useful Improvements in Priming-Cups; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to new and useful improvements in priming cupsfor internal combustion engines and has for its primary object theprovision of means whichwill show the explosion taking place in theengine, so that a person can readily determine if the engine is properlyfunctioning or if any one of the spark plugs employed is not firing.

Another object of this invention is the provision of a priming cup ofthe above stated character, which shall be simple, durable and efiicientand which may be manufactured and sold at a comparatively low cost.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination,and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had tothe following description and accompanying drawings, in which Figure 1is a side elevation of a priming cup constructed in accordance with myinvention,

Fig. 2 is a vertical sectional view of the same.

Referring in detail to the drawings, the numeral 1 indicates acylindrical body having oppositely disposed sight openings 2 formedtherein and has one end formed integrally with a flange 3 that projectsinwardly and outwardly of said body as clearly shown in Fig. 2, and isformed integrally with a pipe or tube 4. The other end of the pipe ortube 4 is threaded within the priming opening 5 of an engine 6. Apacklng or gasket 7 is seated on the flange 3 in the body 1 and has inengagement therewith one Specification of Letters Patent.

end of a transparent tube 8. The tube 8 is constructed from glass or anyother material suitable for the purpose. The upper end of the body 1 isinternally screw threaded to receive the screw threaded neck or' shank 9of a priming cup 10. The priming cup 10 has formed adjacent the neck 9 aflange 11 which abuts the end of the body 1 when said neck is threadedinto the body. A gasket or packing 12 is interposed between the upperend of the tube 8 and the neck 9. By the arrangement of the packings orgaskets 12-and 7 and the neck 9 being threaded into said body forms aleakproof connection between the tube and the body. VThe flanges 11 and3 have their outer peripheries formed to provide wrench engaging facesso that a wrench or similar tool can be employed for connecting anddisconnecting the various parts from each other.

' The priming cup 10 has a passage 13 extending therethrough and whichis controlled by a valve 14 provided with a handle 15. The upper end ofthe priming cup 10 is flared or formed in substantially funnel shape sothat fuel or explosive fluid can be poured into the same and allowed topass through the passage, tube 8 and pipe 4 into the engine for thepurpose of priming the same, and after priming, the valve 14: is closedwhich prevents the explosion and compression of the engine fromescaping. By the sight openings 2 and the transparent tube 8 provided aconstruction which will display or show each explosion taking place inthe engine whereby a person can readily determine if the engine isproperly functioning or if the spark plugs are firing.

While I have shown and described the preferred embodiment of myinvention, it will be understood that minor changes in construction,combination, and arrangement of parts may be made without departing fromthe spirit and scope of the invention as claimed.

Having thus described my invention what I claim is:

A priming cup comprising a cylindrical body having oppositely disposedsight openings, a flange formed on one end of said body and projectinginwardly and out wardly of the same, a pipe formed on said flange and incommunication with the cylinder of an engine, a gasket on said flange Intestimony whereof I afiix my signature lEyithin the body, a transparenttube in said in presence of two witnesses.

ody and restin on said gasket, a second *1 gasket resting oii the otherend of the tube CHARLES ANDERSON 5 Within the body, and'a valved primingcup Witnesses:
